“…Studies through the content analysis of the school texts can roughly be classified into two types: One is the analysis of the methods and contents of the learning (Linton, 1992;Landrum, 1993;Mayer, Sims, & Tajika, 1995), and the other is that of the value and behavior styles of the people in some area or era (Vaughn, Tompkins, Hitchcock, & Oldham, 1989;Peterson & Kroner, 1992;Ortmanns, 1993;Foster & Iannaccone, 1994;Sakita, 1996). These contributions assume that the school texts are important tools for the socialization of children.…”
